AT M E L S Reference Design Based on ATR2406 and ATmega88 Atmel’s reference design addresses the need for cost-effective and flexible cablereplacement solutions, and offers a complete solution allowing fast time-tomarket cycles. It features Atmel's ATR2406 2.4-GHz Smart RF transceiver and the ATmega88 AVR® microcontroller. The proprietary Smart RF firmware implements an adaptive frequency-hopping protocol, enabling robust and reliable data transmission even in a noisy RF environment with interfering signals from WLAN, Bluetooth®, WDCT systems and microwave ovens. The reference design is especially designed to meet the performance and cost requirements of wireless game controllers, but also addresses other wire-replacement applications in the consumer area, such as wireless audio links, interactive intelligent toys and remote controls.
